Grading and Make-ups

Grading Rules for the IPL

A lab session lasts 170 minutes. Once again, you have one week to complete your lab report and return it to your TA’s mail box located in 323 CH. Your TA will return the graded lab book at the beginning of the next lab. Missed labs receive a zero. Students can make-up only one lab during the make-up period at the end of the term and then only if they have a valid excuse for missing that lab. Makeup policy is described in more detail below.

Six experiments have to be done and all six will be used in computing the final course grade. The student will receive a numerical grade (0 – 100) for each lab. At the end of the quarter, the average of the numerical grades is sent to your lecture professor. A 1-credit lab grade will be given independently and this grade will also be counted as 10-15% of your overall lecture course grade. If a student passes the lab component and fails the lecture component, they only need to repeat the lecture component. In that case, the previous lab grade will not be factored into the repeated lecture grade, i.e. the repeated lecture course will be graded from 100% of the repeated lecture component. Students are required to take the two components concurrently as co-requisites, unless they are repeating a component.

Policy on Plagiarism

Do not copy your lab-partner’s write-up or let your partner copy yours. Duplication of text in your electronically submitted report will be checked automatically by the “Turnitin” software, so take this warning seriously. If you are copying text from someone else, or from some other source such as lab manual, textbooks and the Internet – rather than doing your own work, this is considered cheating and will be caught by the “Turnitin” automatic checking system. Copied or duplicate reports will lead to severe penalties (typically a 0 will be given for the lab). This penalty will apply to ALL individuals found to have duplicate text in their reports.

Lab Report Grade Breakdown

  • The grade is based on preparation (5%) for pre-lab quiz and questions, introduction (10%), experimental data and work (25%), analysis, data tables, calculations, graphs, etc. (40%), conclusions (10%) and answers to questions (10%).
  • Honors Sections must answer Honors Questions: Q1&2 are required, Q3=1 extra pt, Q4 = 2 extra pts.
  • Check that your lab grades are posted correctly on Blackboard and report any discrepancies to your TA

Final Grade Ranges

The University grade definitions are: A = outstanding; B = good; C = satisfactory; D = poor; F = fail. Missed labs will receive a zero, which can easily reduce your grade by a full letter grade. Two or more missed labs will likely result in course failure. Typical point spreads for the grades are: A range 90-100, B-range 80-90, C-range 70-80, D-range 55-70, F-range below 55.


Make-ups are difficult to schedule. The TA will not authorize a make-up unless it is fully justified. In rare situations, a make-up will be arranged by your TA and the IPL Supervisor. Because of the heavy lab schedule of the IPL, as well as the fact that your TA has his/her own schedule of classes to attend a make-up may have to take place at a time inconvenient for the student. In no case are you allowed more than one make-up. After you have received approval to make up a lab from the IPL Directors, work with your TA and the Lab Supervisor to schedule the make-up. If you have special problems that your TA may not be able to handle, contact one of the IPL Directors or the Lab Supervisor.

Make-up Policy Summary:

  • Make-ups can be made at the TA’s convenience
  • The due-date is one week from when the lab is performed
  • Final date for all labs to be turned in is April 25th by 11:59pm

Make-up Policy Summary:

  • Missed labs get a zero.
  • Students can make-up only ONE lab during make-up period and only if they had a valid excuse for missing that lab.
  • All make-ups must be approved by the IPL Directors or the IPL Supervisor in consultation with the TA. Approved make-ups can sometimes be scheduled during the term.
  • Make-up dates are April 13-17, or earlier at the TA’s convenience.
  • All make-up lab reports are due April 25th by 11:59pm. NO EXCEPTIONS. No make-up lab reports will be accepted or graded after that time.
  • You must e-mail Tom Hamrick: by April 11th to arrange a make-up lab during the end of term make-up period. Any consecutive two hour and fifty minute time during the make-up period is acceptable. Please include the experiment, day, and time in your e-mail request.
